There is a large diversity in the chemical composition of astronomical objects such as planets, comets, circumstellar ...

Understanding the formation of stars together with their subsequent evolution and identifying the physical processes that ...

Abstract: We give an elementary model for the evolution of dust in galaxies, based on abundance arguments. The model takes account of grain core production in both supernovae and giant stars, and ...

we discuss the implementation of dust physics in our current multiphase model, which also follows the evolution of atomic, ionized and molecular gas. Our goal is to model the conversion rates among ...

The pulsar and its wind move with supersonic speed through the interstellar medium – the stuff (gas, dust and plasma) between the stars. This creates a bow shock: a shock wave of heated gas that ...
